It will depend on the area over which the water and the surrounding are in contact.
Assuming the water is in a container, part of the contact surface will be the container and here the thermal conductivity of the material of the container will be relevant.
-- the area of the exposed surface -- the airflow over the exposed surface -- the temperature of the liter of water -- the air pressure at the exposed surface -- the relative humidity of the air in the room -- the transparency of the liter container are all relevant to the rate of evaporation.
The temperature of the resulting mixture will be 20 degrees. Mixing equal amounts of the same temperature water does not change the overall temperature of the system.
The time it takes for one liter of water to freeze will depend on various factors such as the temperature of the surroundings and the initial temperature of the water. Generally, it can take a few hours to freeze completely in a standard home freezer at around -18 degrees Celsius.
There are 1000 cm^3 in a liter of water at room temperature.
Impossible to say without knowing three things: the kind of container it's in, the ambient air temperature, and the starting temperature of the water. A cup of boiling water in a sealed thermos that someone put in an oven heated to 100 degrees will take far longer to cool to 78 degrees F (in fact, it never will cool to 78 degrees; it can't get any colder than the ambient air temp, which is 100 degrees) than a cup of 80-degree water in an aluminum canteen cup you stuck in the freezer.
The length of time will depend on the temperature scale used. It will also depend on the amount of water, the surface area which in contact with air, atmospheric pressure, wind speed, ambient humidity and so forth.
If one were to pour a liter of water at 40 degrees C into a liter of water at 20 degrees C, the final temperature of the two liters of water becomes 30 degrees C. This is because the free energy capacity, or heat carrying capacity of the two additives are the same, since they are both water.
What is the ambient temperature of the water?
-- the area of the exposed surface -- the airflow over the exposed surface -- the temperature of the liter of water -- the air pressure at the exposed surface -- the relative humidity of the air in the room -- the transparency of the liter container are all relevant to the rate of evaporation.
Ambient refers to the temperature of the surrounding air, i.e not at parking lot level etc. Ambient means the temperature not being effected by mechanical means, like AC or any heat source. example, if you serve a wine at ambient temperature, it is not a specific number it is what ever the room is at the time.
The temperature of the resulting mixture will be 20 degrees. Mixing equal amounts of the same temperature water does not change the overall temperature of the system.
The amount of propane needed to heat a 50 gallon water heater from 75 degrees to 105 degrees would depend on factors such as the efficiency of the water heater, the starting temperature of the water, and the ambient temperature. It is difficult to provide an exact amount without this information.
The temperature of the water will be the ambient (room) temperature. A broken piece of cutlery makes no difference to the temperature.
temperature has nothing to do with it. 1 liter of anything = 1 liter, it's as simple as that. Just like 1 quart of anything = 1 quart.
The time it takes for one liter of water to freeze will depend on various factors such as the temperature of the surroundings and the initial temperature of the water. Generally, it can take a few hours to freeze completely in a standard home freezer at around -18 degrees Celsius.
One milligram, if the water is at 4 degrees Centigrade. At any other temperature, the water will weigh a bit less.
There are 1000 cm^3 in a liter of water at room temperature.
